PLUMBING SYSTEM.

Application filed January 16, 1922.

To all whom it may concern:

Be it known that I, .EDVVARD KENNEDY,

a citizen of the United States and a resident of New York city, county and State of 5 New York, have invented a certain new and a useful Improvement in Plumbing Systems,

of which the following is a specification.

This invention relates to an improved plumbing system and has for one of its objects to provide a system which can be easily installed in the walls of a building for discharging. and venting a plurality of plumbing fixtures at each floor.

One of the particular objects of the invention is to provide an improved unit fitting which is of such construction that the main discharge and vent connections from the bath tubs arranged in the flooring and in vertical alignment with each other. The new unit section in one embodiment of the invention is composed of parallel discharge and vent pipes andan interposed parallel discharge receiving pipe arranged therebetween and in communication at its upper end with the main vent pipe. These pipes are integrally connected with each other and have common separating or partition webs so that the arrangement is very compact whereby the fitting will occupy a minimum of space in the wall. The intermediate discharge and vent pipe is contracted at its upper end which communicates with the main vent pipe and the packing receiving hubs on the upper ends of the main Waste and vent pipes are integrally connected at their inner sides. This provides a very strong and durable structure atthe end of the fitting for connection to the lower end of the fitting unit immediately above and of the joints. 7

It is a further object of the invention to provide in a plumbing system. standardized unit fittings for connection to each other, wherein the number of jointed connections is reduced to a minimum and in which the several units are so constructed as to adequately take care of the discharge of a number of fixtures and also properly vent the same without back pressure resulting in clogging, and the escape of obnoxious odors through the outlets of the fixtures.

With the above and other objects in view, the invention consists in the improved plumbing system and in the form, construcgreatly facilitates easy and quick packing Serial No. 529,422.

tion and relative arrangement of the several unit parts thereof as will be hereinafter more fully described, illustrated in the accompanying drawings and subsequently incorporated in the subjoined claims.

In the drawing wherein I have disclosedone practical and satisfactory embodiment of the invention and in which similar reference characters designate corresponding parts throughout the several views,

Figure 1 is a vertical sectional view with parts in elevation illustrating an installation of my improved plumbing system in a building Fig. 2 is a horizontal section taken on the line 2-2 of Fig. 1; and

Fig. 3 is a horizontal section taken on the line 33 of Fig. 1.

In the drawing I have shown one of the intermediate units 5 which extends through each of the floors between the lowermost room and the uppermost room of a building and is concealed and enclosed within the partition wall separating adjacent rooms from each other, The uppermost unit 5 is connected to the unit 6 extending through the roof of the building by a unit 7 and the lowermost unit 5 is connected to the soil or drainage pipe by a unit 8 extending through the floor of the lowermost room of the building. As will hereinafter appear, there are certain differences in structural detail between these unit sections 5, 6, 7 and 8.

Each of the sections 5 consists of a waste pipe 9 and a vent pipe 10, said pipes extending in parallel relation. Between the upper portions of the pipes 9 and 10, a second waste pipe or passagell is interposed, said passage being separated from the passages of the pipes 9 and 10 by the common partition or division webs 12. The upper. end of the passage 11 is contracted by obliquely inclining one of the webs 12, such inclined portion of the web having an opening 13 therein affording communication between the upper end of the passage 11 and the vent pipe 10. The unit fitting 5 is adapted to be disposed through an opening provided therefor in the fioor indicated at F, said fitting having a waste connection 14 in the line of the floor which is adapted to be connected by a suitable coupling means to the closet bowl. Also, a waste pipe 15 from a tub or other stationary fixture may be extended through the floor and coupled to one side of the connection 1 1. The waste con nection 14 communicates with the lower end of the passage 11 and with the waste pipe 9, the water passing downwardly through the waste pipe, while the air and gases are vented through the passage 11 and opening 13 into the upper end of the vent pipe 10.

A waste pipe 15 extending from another plumbing fixture is connected to the intermediate pipe 11. A vent pipe 16 for the fixture to which pipe 15 is connected opens into the upper end of the pipe 10.

contracting the upper end of the passage 11, the hubs 17 on the upper ends of the pipes 9 and 10 may be brought close together. In fact, at their inner sides the walls of these hubs are integrally formed. This provides a very durable construction and facilitates the easy and quick application of the packing, material for sealing the joint between the upper end of the unit 5 and the lower end of the unit 7 which connects the vertically spaced units 5 with each other. Each of the unit sections 7 also consists of a waste pipe 18 and a vent pipe 19 which form continuations of the pipes 9 and 10 respectively. The lower ends oithese pipes 18 and 19 are slightly spaced. apart, the re- "mainingportions of the pipes having a com mon dividing or separating wall 20 which terminates short of the spaced lower end portions of said pipes to provide a communicating opening 21 therebetween. At their upper ends, the pipes 18 and 19 are likewise formed with integrally connected hubs 22 which receive the spaced lower end portions 23 of the unitsection 5 below the floor F, while the lower ends 01 the pipes 18 and 19 of'the sections 7 are fitted in the hubs '17 on the upper ends of the pipes 9 and 10. A suitable seal, preferably of lead, is packed into the hubs 17 and 22 to tightly seal the joint connections between the several unit sections.

The unit 6 which extends through the flooring of the upper room of the building is likewise provided with parallel waste and vent pipes 24 and 25respectively, similarin form and construction to the unit sections 7, except that at the upper end of the waste pipe 24 where it passes through the roof of the building, the vent pipe 25 is connected to said waste pipe and opens into the same through one side thereof, as at 26. In this case the waste connection 15 is made tothe waste pipe 24 as this unit section 6, like the section '7, is not provided with the intermediate waste and vent passage 11.

The unit section S'extendingthrough the floor of the lower room of the building is substantially of the same construction as the uppermost unit 6, having the waste and vent pipes 27 and 28 respectively with connections.

from the stationary fixtures similar to those above referred to in connection with the intermediate unit sections 5. Immediately below the waste connection l l-f of the section 8 which is in line with the floor, the vent pipe 28 opens through the side of the waste pipe 27. Below the floor the unit section 8 is connected in the usual manner to the soil pipe leading to the underground drainage pipe.

When the several unit sections of the fitting are assembled in the building wall in its erection, it will be observed that all of the waste pipe connections 14 which are located in the floor, are disposed in vertical alignment with each other. 'Thus theconnecting couplings between the waste connections and the outlets of the closet bowls may all be of identically the samestandard size and'shape. A further advantage incident to the construction of the several unit sections as above described resides in the increased rigidity ing regulations, and preferably, the passagev 11 is of greaterVa-rea than required so that there will be no danger of back pressure through this passage by the flow of water in maximum volume into 7 the waste pipe 9 through the connection 14:.

From the foregoing description consid" ered in connection with the accompanying drawing, the constructlon, arrangementiand several advantages of the present invention will be clearly and fully understood. -By means of my'improvements-relatively complicated plumbing systems may be installed in. the erection of a building with a minimum of manual labor and with a realiza tion of appreciable economy in time and money. I have above specifically described the manner in which the plurality ofjpluinbing fixtures are connected tothe'fitting but numerous mechanical variations in this respect might be adopted. Thus for instance in some cases it may be found advisable to provide a separate Waste pipe for the bowl connections 14 in which case, the'bore of the several pipes or passages of the unitsections might be somewhat'reduced intli'ameter. "It

will further be manifest that the invention asherein disclosed is susceptible o'f-embodiment in other structural forms and I accordingly reserve the'privilege of resorting to all such legitimate changes inthe form, construction and relative arrangement of the several parts as may be fairly embodied within the spirit and scope of the invention as claimed.

I claim:

1. A unit for plumbing systems consisting of parallel waste and vent pipes having no communication with each other and an additional combined waste and vent pipe between the same and formed integral therewith and the upper end of the combined waste and vent pipe drawn inwardly and having an opening communicating with the main vent pipe, the additional combined Waste and vent pipe having communications with the waste pipe and a. socket communicating with the main waste pipe and the lower end of the additional vent pipe midway between the same.

2. A unit for plumbing systems consisting of parallel waste and vent pipes having no communication with each other and an additional combined waste and vent pipe formed between the same and integrally therewith, the upper end of the additional waste pipe communicating with the vent pipe and the lower end communicating with the waste pipe, a pipe socket communicating with the main waste pipe and the lower end of' the additional vent pipe mid-Way hetween the same and means carried by the additional waste pipe intermediate its ends for connecting the vent pipe thereto.

3. A unit for plumbing systems consisting of parallel waste and vent pipes having no communication with each other and an additional combined waste and vent pipe between the same and formed integral therewith, the upper and lower ends of the vent pipe being drawn inwardly close to the waste pipe a communication between the upper end of the additional waste pipe and the main vent pipe and a communication between the lower end of the additional "waste pipe and the main waste pipe, a connection communicating with the lower end of the additional vent pipe and the main waste pipe mid-way between the same, a waste pipe connection carried by said connection and a vent pipe connection carried by the additional vent pipe between its upper and lower ends.

In testimony that I claim the foregoing as my invention, I have signed my name hereunder.

EDWARD KENNEDY.
